Hog4PC Touchscreen Calibration

I have a Hog3PC with wings and 4 elo 19" 1915L touchscreens.

For the life of me, I can't seem to get the hog 4 software to display the touchscreen calibration buttons. I have tried both elo drivers, the one for multitouch and win7 and the singletouch driver for win7. Regardless of what I do, I never get the option in hog4/control panel/display to calibrate the touchscreens.

Three questions..

1. Am I doing something wrong?

2. Is Touchscreen Calibration not implemented in Hog4 PC yet?

3. If it's not implemented in Hog4PC, will it be implemented?

Thanks ahead of time for any replies.
